Abstract
A recreational vehicle includes an interior space having a floor, a first insulating member located below the floor, a second insulating member located below the floor, a chassis located at least in part between the floor and the first insulating member and the floor and the second insulating member, a first enclosed volume defined by the floor, the chassis and the first insulating member, a second enclosed volume defined by the floor, the chassis and the second insulating member, an air flow path between the first enclosed volume and the second enclosed volume, and an air flow path between the interior of the recreational vehicle and the first enclosed volume.
Claims21
A recreational vehicle having a front end, a rear end, a first side extending from the front end to the rear end, a second side extending from the front end to the rear end opposite the first side, a chassis, and a floor located above the chassis, the chassis including:
- a first side frame member extending along the first side of the recreational vehicle from the front end to the rear end, the first side frame member having an upper surface and a lower surface;
- a second side frame member extending along the second side of the recreational vehicle from the front end to the rear end, the second side frame member having an upper surface and a lower surface;
- a first cross member;
- a second cross member;
- a third cross member connected to the first side frame member and the second side frame member adjacent the front end of the recreational vehicle;
- a fourth cross member connected to the first side frame member and the second side frame member adjacent the rear end of the recreational vehicle;
- the first cross member connected to the first side frame member and the second side frame member between the third cross member and the fourth cross member, the first cross member having a an upper surface, a lower surface, a front surface, a rear surface and an opening extending through the first cross member from the front surface to the rear surface;
- the second cross member connected to the first side frame member and the second side frame member between the first cross member and the fourth cross member, the second cross member having a an upper surface, a lower surface, a front surface, a rear surface and an opening extending through the second cross member from the front surface to the rear surface;
- a first split cross member connected to the first side frame member and the second side frame member between the first cross member and the second cross member, the first split cross member having an upper member and a lower member positioned below the upper member so as to form a space between the upper member and the lower member;
- a second split cross member connected to the first side frame member and the second side frame member between the first split cross member and the second cross member, the second split cross member having an upper member and a lower member positioned below the upper member so as to form a space between the upper member and the lower member;
- a first bracket connected to first side frame member;
- a second bracket connected to second side frame member;
- a third bracket connected to the first cross member;
- a fourth bracket connected to the second cross member;
- a first insulating member connected to the lower surface of the first side frame member, the second side frame member, the first cross member and the third cross member so as to form a first enclosed volume between the floor, the first insulating member, the first side frame member, the second side frame member, the first cross member and the third cross member;
- a second insulating member connected to the first bracket, the second bracket, the third bracket and the fourth bracket so as to form a second enclosed volume between the floor, the second insulating member, the first side frame member, the second side frame member, the first cross member and the second cross member;
- and
- a third insulating member connected to the lower surface of the first side frame member, the second side frame member, the second cross member and the fourth cross member so as to form a third enclosed volume between the floor, the third insulating member, the first side frame member, the second side frame member, the second cross member and the fourth cross member.
